Figure 25. AD8184AR Evaluation Board
E VALUAT ION BOARD
An evaluation board is available for the AD8184. It has been
carefully laid out and tested to demonstrate the specified high
speed performance of the devices. Figure 25 shows the sche-
matic of the evaluation board. For ordering information,
please refer to the Ordering Guide.
Figure 26 shows the silkscreen of the component side and Fig-
ure 28 shows the silkscreen of the solder side. Figures 27 and 29
show the layout of the component side and solder side respectively.
T he evaluation board is provided with 49.9
termination resis-
tors on all inputs. T his is to allow the performance to be evalu-
ated at very high frequencies where 50
termination is most
popular. T o use the evaluation board in video applications, the
termination resistors should be replaced with 75
resistors.
T he FR4 board type has the following stripline dimensions:
60-mil width, 12-mil gap between center conductor and outside
ground plane “island” and 62-mil board thickness.
T he multiplexer output is loaded with a 4.99 k
resistor. For
connection to external instruments, an oscilloscope probe
adapter is provided. T his allows direct connection of an FET
probe to the board. For verification of data sheet specifications,
use of an FET probe is recommended because of its low input
capacitance. T he probe adapter used on the board has the same
footprint as SMA, SMB and SMC type connectors, allowing
easy replacement if necessary.
T he side-launched SMA connectors on the analog and digital
inputs can also be replaced by top-mount SMA, SMB or SMC
type connectors. When using top-mount connectors, the
stripline on the outside 1/8" of the board edge should be re-
moved with an X -acto blade as this unused stripline acts as an
open stub, which could degrade the small-signal frequency re-
sponse of the multiplexer.
Input termination resistor placement on the evaluation board is
critical to reducing crosstalk. Each termination resistor is ori-
ented so that the ground return currents flow counterclockwise
to the ground plane “island.” Although the direction of this
ground current flow is arbitrary, it is important that no two in-
put or output termination resistors share a connection to the
same ground “island.”
